Ratio of pore pressure change to original due to depletion
Input(s)
P: Change in Pore Pressure (psi)
\(S_{\text {hmax }}\): Maximum Horizontal Stress (psi)
\(S_{\text {hmin }}\): Minimum Horizontal Stress (psi)
Output(s)
q: Pore Pressure Ratio (fraction)
Formula(s)
\[
\mathrm{q}=\frac{\mathrm{P}_{\mathrm{p}}}{\mathrm{S}_{\mathrm{hmax}}-\mathrm{S}_{\mathrm{hmin}}}
\]
